Answer 2

Pericardial sac

Question 3

How many lobes does the left lung have?

Answer 3

Two

Question 4

How many lobes does the right lung have?

Answer 4

Three

Question 5

The respiratory tract is an open body cavity, so it is lined with

Answer 5

Mucous membranes

Question 6

Thoracic cavity is a closed body cavity, so it is lined with

Answer 6

Serous membranes

Question 7

What is the serous membrane that surrounds the lungs?

Answer 7

Pleura

Question 8

The Visceral Layer of the lung lies

Answer 8

Against the lung

Question 9

The Parietal Layer of the lung lines

Answer 9

The body cavity

Question 10

Serous membranes are

Answer 10

Double membranes with empty space in between, or the pleural cavity

Question 11

Body cells need Oxygen for

Answer 11

Cellular respiration (to make ATP)

Question 12

What are the four parts of respiration?

Answer 12

1. Pulmonary Ventilation
2. Alveolar Gas Exchange
3. Gas Transport
4. Systemic Gas Exchange

Question 13

What happens during Pulmonary Ventilation?

Answer 13

Air containing O2 moves into lungs, whereas CO2 air leaves lungs

Question 14

What are the two steps of Pulmonary Ventilation?

Answer 14

1. Inspiration

2. Expiration

Question 15

What happens during Alveolar Gas Exchange?

Answer 15

There is gas exchange at respiratory membrane in the alveoli

Question 16

With what does diffusion happen with in Alveolar Gas Exchange?

Answer 16

In body cells, with O2 diffusing into and CO2 diffusing out

Question 17

The Circulatory system kicks in during which step of respiration?

Answer 17

Gas Transport

Question 18

Gas Transport involves

Answer 18

Blood being moved around the body

Question 19

Systemic Gas Exchange is

Answer 19

Gas exchange at body tissues

Question 20

What is Boyle’s Law?

Answer 20

PiVi = P2V2

Question 21

Air moves down the pressure gradient from

Answer 21

High pressure to low pressure

Question 22

When you breathe in, the volume of lungs

Answer 22

Increases

Question 23

Diaphragm will contract when

Answer 23

You inspire

Question 24

What happens when the diaphragm contracts?

Answer 24

• It will move down and extend ribs

- Increases volume of thoracic cavity

Question 25

The Pleural cavity of lungs will cause for

Answer 25

Lung expansion during inspiration

Question 26

Gas exchange within the body can be

Answer 26

• Alveolar

- Systemic

Question 27

Alveolar gas exchange happens between

Answer 27

Gases in blood capillaries and gas in alveolus

Question 28

Systemic gas exchange happens between

Answer 28

Body tissues and capillaries

Question 29

What is Dalton’s Law?

Answer 29

Ptotal = P1 + P2

Question 30

Henry’s Law states that the solubility of a gas in a liquid depends on

Answer 30

• Partial pressure of the gas in the air

- Solubility coefficient of the gas in the liquid

Question 31

The amount of CO2 will enter body depends on

Answer 31

• Pressure gradient

- Solubility of CO2

Question 32

Gases leave solution faster in

Answer 32

Warmer temperatures

Question 33

Oxygen goes from alveoli into blood capillaries due to

Answer 33

Partial pressure gradient

Question 34

What is the partial pressure in alveoli?

Answer 34

104 mmHg

Question 35

What is the partial pressure in capillaries?

Answer 35

40 mmHg
